Begin the deck with 2x4s, pressure-treated, by attaching them to the frame vertically by employing a framing nailer. Install two 9-foot side pieces and lay them beside each other before installing two 4-foot end pieces. Mark each location of the joists to make sure that they will be evenly spaced at exactly 16 inches, then secure the end pieces and secure the joists to the frame using the framing nailer. Next, install 5/4″ decking to secure the decking boards using a screw gun. Install each with the cleaner side facing upwards, and install the first board along the edge and allow it to overhang the frame’s edge by half an inch.
Using the complete deck as a work surface, begin building the walls by laying out 8-foot-tall wall panels for the sides, top plate, bottom plate and studs that are spaced at 16 inches. Secure them together using a nail gun and repeat this process until the wall panels are finished. Nail them to the deck to raise the walls and scan the structure using a framing square. Build two more narrow panels for the wall that will hold the door using two 2x4s for the side for more strength on either side.
After both the front wall panels are set in the constructing a storage shed and the structure is finished, add 2x4s across the top to make a double top-plate. This will ensure that the shed is stronger. Once all the wall panels are done hang 4″x8″ sheets of OSB siding for the outside.
To make the roof rafters cut 2×6 boards and make them 13 inches long at the center. Now secure them with cleats made from OSB. Raise and attach them to the headers, then use 1×6 strips for the tops of the rafters and tie them to add support for the roofing sheets. Next, nail down the roofing sheets with self-sealing nails and washers.
After the completion of the boxes, cut holes for the windows and the storage boxes using a reciprocating saw. To make specific cuts through the OSB, cut between the studs. Next, attach vinyl siding to the outside of the shed using the manufacturer’s instructions. Starting at the corners, work your way to the middle and secure the siding using nails to the OSB.
Now once the main steps to construct a storage shed are completed, the doors and any storage pieces can be added. Make the two doors from one sheet of 3/4″ plywood that will be cut in half and has a 1″x4″ trim for the outer frame and barn-style “X” braces. Use 1/2″ plywood for the storage pieces that will be fastened with glue and nails for securing previously cut openings. Having a ramp to use for the front door will make it easier to store and retrieve tools such as mowers.
